vkCmdSetDepthBias(3)

C Specification

To dynamically set the depth bias parameters, call:

// Provided by VK_VERSION_1_0
void vkCmdSetDepthBias(
    VkCommandBuffer                             commandBuffer,
    float                                       depthBiasConstantFactor,
    float                                       depthBiasClamp,
    float                                       depthBiasSlopeFactor);

Parameters

commandBuffer is the command buffer into which the command will be recorded.
depthBiasConstantFactor is a scalar factor controlling the constant depth value added to each fragment.
depthBiasClamp is the maximum (or minimum) depth bias of a fragment.
depthBiasSlopeFactor is a scalar factor applied to a fragment’s slope in depth bias calculations.

Description

This command sets the depth bias parameters for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with VK_DYNAMIC_STATE_DEPTH_BIAS set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the corresponding VkPipelineRasterizationStateCreateInfo::depthBiasConstantFactor, depthBiasClamp, and depthBiasSlopeFactor values used to create the currently active pipeline.

Calling this function is equivalent to calling vkCmdSetDepthBias2EXT without a VkDepthBiasRepresentationInfoEXT in the pNext chain of VkDepthBiasInfoEXT.

Valid Usage

VUID-vkCmdSetDepthBias-depthBiasClamp-00790
If the depthBiasClamp feature is not enabled, depthBiasClamp must be 0.0

Valid Usage (Implicit)

VUID-vkCmdSetDepthBias-commandBuffer-parameter
commandBuffer must be a valid VkCommandBuffer handle
VUID-vkCmdSetDepthBias-commandBuffer-recording
commandBuffer must be in the recording state
VUID-vkCmdSetDepthBias-commandBuffer-cmdpool
The VkCommandPool that commandBuffer was allocated from must support graphics operations
VUID-vkCmdSetDepthBias-videocoding
This command must only be called outside of a video coding scope

Host Synchronization

Host access to commandBuffer must be externally synchronized
Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized
